"There's no kill like OVERKILL!
Meet the Lionhearts.
A smack-talking rag-tag band of rebels bound on an impossible quest. With an arsenal of outrageous weapons, they're destined for victory in 12,000 bullets or less. If they can make it through an army of psychotic robots and wall-smashing Goliaths, they just might save the world... if they don't burn it first.
Navigate through a richly entertaining story with your smack-talkin' partners in crime.
Explore five diverse environments including icy and snowy regions, mountains with breathtaking vistas, deep and foreboding woods, and rain-spattered cliffs.
Take down wicked enemies like half-man, half-animal Grunts, eliminator droids, wall-smashing Goliaths, evil monks and wild twiglets.
Shoot your way through 21 action-packed missions.
Brandish over 17 outlandish weapons like the Topsy-Turvy, the Vindaloo Rocket Launcher, or the Worlds Smallest Black Hole and the Land Shark Gun.
